Abstract

Invention concernant le freinage des véhicules. Système de freinage anti-patinage à actionnement par fluide sous pression, comprenant un système de soupapes pour relâcher la pression lorsque la décélération est exagérée. Ce système comprend deux soupapes 1, 2 commandées par diaphragme branchées dans la communication 8, 9, 10 et chaque soupape est commandée indépendamment par la décélération. Application aux véhicules ferroviaires.Invention concerning the braking of vehicles. A pressurized fluid actuated anti-skid brake system, comprising a valve system for relieving pressure when deceleration is exaggerated. This system includes two diaphragm-controlled valves 1, 2 plugged into communication 8, 9, 10 and each valve is independently controlled by deceleration. Application to railway vehicles.
